一种高增益交错耦合电感直流变换器
A High Gain Interleaved Coupled-inductor DC/DC Converter
摘要
Abstract
A novel high step-up interleaved dc-dc converter topology with two coupled-inductors is presented for low input voltage and high input current applications, such as photovoltaic and fuel cell generation systems. In the proposed converter, the primary currents of two coupled-inductors are interleaved in parallel at input, which reduces the input current ripple. The secondary sides of two coupled-inductors are connected in series with a capacitor for a double voltage cell to improve the voltage gain further. Moreover, this structure can also reduce the voltage/current stresses of active switches and diodes. The leakage energy can also be recycled by the two output capacitors, which are charged interleaving in parallel and discharged in series. In addition, the reverse-recovery problems of diodes are alleviated significantly by the leakage inductance. The operating principle and the steady-state characteristics are discussed in detail to show the merits of the presented converter and the corresponding model is also derived. Finally, a rating prototype system is constructed to verify the effectiveness of the proposed converter.关键词
